Anyone know the answer to this algebra problem?

ikadub [295]

Answer: $\bold{a=1\qquad b=\dfrac{1}{16}\qquad c=\dfrac{1}{64}\qquad d=1\qquad e=\dfrac{4}{9}\qquad f=\dfrac{16}{81}}$

<u>Step-by-step explanation:</u>

$\begin{array}{c|l}\underline{\quad x\quad}&\underline{\quad 4^{-x}\qquad \qquad}\\-1&4^{-(-1)}=4^1=4\\\\0&4^{-(0)}=4^0=1\\\\2&4^{-(2)}=\dfrac{1}{4^2}=\dfrac{1}{16}\\\\4&4^{-(4)}=\dfrac{1}{4^4}=\dfrac{1}{64}\end{array}$

$\begin{array}{c|l}\underline{\quad \bigg x \quad}&\underline{\quad \bigg(\dfrac{2}{3}\bigg)^x\qquad \qquad}\\\\-1&\bigg(\dfrac{2}{3}\bigg)^{-1}=\dfrac{3}{2}\\\\0&\bigg(\dfrac{2}{3}\bigg)^{0}=1\\\\2&\bigg(\dfrac{2}{3}\bigg)^{2}=\dfrac{2^2}{3^2}=\dfrac{4}{9}\\\\4&\bigg(\dfrac{2}{3}\bigg)^{4}=\dfrac{2^4}{3^4}=\dfrac{16}{81}\end{array}$

The equation of a circle is (x + 3)2 + (y + 5)2 = 8. Determine the coordinates of the center of the circle.

Illusion [34]

The equation of the circle is written as: (x - h)² + (y - k)² = r²

(h,k) are the points of the center of the circle.
r is the radius.

In case of the given equation the center is (-3,-5)

Hope this helps :)

laws of Sines all together. Find each measurement indicated. Round your answers to the nearest tenth. Part 1 Please show your wo

erik [133]

Answer:

1. 23.0 cm

2. 21.0 ft

3. 31.0 yd

Step-by-step explanation:

1. 30/sin110 = RT/sin46

RT = sin46 × 30/sin110

RT = 22.96516279

2. Angle A = 180 - 61 - 53 = 66°

24/sin66 = AB/sin53

AB = sin53 × 24/sin66

AB = 20.98116966

3. 18/sin28 = HP/sin54

HP = sin54 × 18/sin28

HP = 31.01850475

Dentify the percent, amount, and base in this problem. 75% of what number is 30?

anastassius [24]

Answer:

Step-by-step explanation:

This is essentially just (4/3), or $\frac{3}{4}^{-1}$ . (4/3)*30 = 40, so our answer must be 40. Just to check, taking 75 percent of 40, we indeed get 30!
